ROTARY MOTOR.

aPECIFICATION forming part of Letters Patent No. 469,404, dated February23, 1892-.

' Application filed August 31, 1891. Serial No. 404,177- (No model.)

To to whom it mat concern:

Be it known that I, CHARLES S. IRISH, of Jordan, in the county ofOnondaga, in. the State of New York, have invented new and usefulImprovements in Rotary Motors, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the class of motors in which a wheel inclosedin a case receives rotary motion from water under pressure ad mittedinto said case; and the invention consists in an improved constructionand combination of parts, as hereinafter described, and set forth in theclaims.

In the annexed drawings, Figure 1 is an edge View of a motor embodyingmy invention. Fig. 2 is a side view of the same with the front sideplate removed to expose the interior of the case with the wheeljournaled Fig. 3 is a transverse section on line :0 at, Fig. 2. Fig. 4is an enlarged sectional view of one of the discharge-nozzles of thewater-wheel and the adjacent buckets of the case; and Fig. 5 is atransverse section on line y y, Fig. 4.

Similar letters of reference indicate corresponding parts.

A represents an annulus, the inner side of which is formed with a seriesof buckets a a a, distributed around the said annulus. These buckets areof the form of recesses or depressions, each of which is slopedgradually from one side and terminated abruptly at the opposite side forthe purpose hereinafter explained. To opposite sides of said annulus aresecured the plates A A, which are concave on their inner sides andformed with waterexits b b, as shown in Fig. 3 of the drawings. Saidannulus, with the side plates attached thereto, constitutes the case,which is secured stationary in its position and incloses the rotarywater-wheel O. The hub of this wheel is formed with a cylindrical axialcavity extending from one end of the hub partway toward the opposite endthereof, where said hub has the shaft j extending from it. To provideproper axial supports for said wheel, I form one of the side plates Awith a tubular hub h, through which the shaft j extends, and the otherside plate A, I form with an inwardly-extending hollow journal 2',enter- 3 of the drawings.

ing the axial cavity of the wheel-hub. The wheel is thus provided withtwo separate and distinct axial supports, one of which is asolid shaftfixed to the wheel and journaled in the hollow outward projecting hub ofthe case and the other consisting of the hollow journal projectinginward from the case and e11- tering the hub of the wheel, as shown inFig. Said journal is open at its outer end, and to the exterior of theside plate A is secured a collar D, to which is connected the pipe P,which admits under pressure either Water or air or steam, as may bedesired, to employ as the motive power.

To relieve the wheel 0 from side pressure by the force of the water orair or steam entering the journal 2', I close the inner end thereof andprovide slots 2' t" z" for the exit of the aforesaid substance throughthe sides of the journal, as shown in Fig. 3 of the drawings.

The wheel 0 is formed with hollow radial arms 0 0', preferably curved inopposite direct-ions fromwhich the wheel is to turn, as shown in Fig. 2of the drawings. The free end of each arm 0' is provided with .adischarge-nozzle n, which is formed with a segmental closed portion 0, alip e, extending from said closed portion in opposite direction fromwhat the wheel is to rotate, and an offset e at the junction of theaforesaid lip and the closed portion, in which offset is a slot or port0 for the escape of the water or air or steam which is directed towardthe abrupt sides of the buckets a a. To guide thewater or aforesaidsubstance more effectually in said direction, I provide the sides of thenozzle n with flanges Z, as shown in Fig. 5 of the drawings. The wateror air or steam passes from the journalt' through the arms (3' O andnozzles 77. n and impinges the abrupt sides of the buckets a do, and bythe resistance presented by the latter to the water or aforesaid motivepower transmits the power to the Wheel 0, which thus receives rotarymotion. To utilize this motion, a pulley p or a suitable gearwheel isattached to the shaft j, as shown in Fig. 1 of the drawings.

To allow the water-Wheel O to be adjusted so as to compensate for thewear on the nozzles n n and maintain the latter in contact with theannulus A, I make the wheel-arms extensible longitudinally, preferablyby inserting the shanks of the nozzles longitudinally movable into thearms 0' O and inserting through the sides of the arms set-screws 0 0,Which engage the shanks of the nozzle.

WVhat I claim as my invention is 1. The improved motor, consisting of anannular case secured stationary in its position and having directly onits inner peripheral Wall a series of buckets distributed around saidwall and held stationary therewith, in combination with a revolubleWheel inside of the case, havinga hollow hub and hollow arms extendingfrom the hub and terminating with nozzles facing the buckets of thecase, and a supply-pipe communicating With said hub, as set forth.

2. In combination with the rotary hollow Wheel (1, having arms 0' 0provided with discharge-nozzles n n at their free ends, and thesupply-pipe communicating with the cavity of the hub of said Wheel, theinclosing case secured stationary in its position and composed of theannulus A, formed With buckets a a a, and separate plates A A, securedto opposite sides of said annulus, substantially as described and shown.

3. In combination with the stationary annulus A, formed with the bucketsa a a, the rotary hollow wheel 0, having hollow arms G, nozzles n 71,connected longitudinally movable to said arms, and set-screws 0,connected to the wheel-arms and securing there signed my name this 25thdayof August, 1891.
